PT1323543E - Method for applying thin security elements on heat-sensitive substrates and intermediate products obtained thereby - Google Patents

Abstract

Thin-layer security elements (5) are transferred from a carrier foil (6) onto a substrate material (2) in a hot-press procedure. Uncoiled onto an intermediate product spool (11) together with the substrate material, the carrier foil acts as a separating layer between the security elements transferred onto the substrate material and the substrate material for an adjacent winding point. An Independent claim is also included for an intermediate product as a spooled product for producing valuable documents.

Claims (10)

A method of applying thin-layer security elements (5) onto heat-sensitive substrates (12) comprising the following steps: - Adhesion of the thin-layer security elements (5) onto a support material (6) (6) and the substrate material (2) under the application of pressure and heat, in such a way that, on the one hand, the thin layer security elements (5) adhere to a surface of the substrate material (2) and, on the other hand, the support material (6) is removable from the thin layer security elements (5), and - winding of the substrate material (2) together with the support material (6) to obtain an intermediate roll (11). Process according to claim 1, further comprising the following steps: - unwinding of the substrate material (2) with the support material (6) of the product roll (11) - separating the support material (6) from the substrate material (2) such that the thin layer security elements (1) remain on the support material (2), and Trim the substrate material into substrates (12) which can be manipulated separately. A process according to claim 1 or 2, wherein the substrate material (2) on its side opposite the thin layer security elements (5) has a thermoplastic adhesive layer (4). A process according to claim 3, wherein the substrate material (2), before or after the cutting step, under application of pressure and heat, is laminated to other layers. A method according to any one of claims 1 to 4 for the production of value documents, selected from the following set of value documents: debit cards, credit cards, identification cards, banknotes, checks, identity cards , transportation tickets, entrance tickets. A method according to any one of claims 1 to 5, wherein the thin layer security elements (5) are selected from the group of security elements: magnetic stripes, security threads, optical variation layers, holograms, networks of diffraction, latent images, layers of pearly pigmented layers, layers with crosslinked liquid crystals, layers of optical interference. 2 7. Intermediate product as roll product (11) for the production of valuable documents such as debit cards, credit cards, identification cards, banknotes, checks, identity cards, transport tickets and entry tickets covering one (6) with thin layer sealing elements (5) and a thermosensitive substrate material (2) on the surface of which adheres the thin layer security elements (5), characterized in that the material (6) ) is removable from the thin layer security elements (5). An intermediate product according to claim 7, wherein the substrate material (2) on its side opposite the thin layer security elements (5) has a thermoplastic adhesive layer (4). The intermediate product of claim 7 or 8, wherein the thin layer security elements (5) are selected from the following group of security elements: magnetic stripes, security threads, optical variation layers, holograms, networks of diffraction, latent images, pearly pigmented layers, layers of liquid crystals, layers of optical interference. A process for continuously laminating continuous sheets for the production of value documents in which at least two sheet paths are joined and continuously connected to one another, wherein at least one of the continuous sheets has a heat-sensitive substrate and an element of The thin layer security disposed thereon and in accordance with any one of claims 7 to 9 is unwound from a roll as an intermediate product, and a web-shaped carrier material, first disposed on the security elements, is spaced apart from the carrier. thermosensitive substrate and the thin layer security elements upon unwinding of the intermediate product and prior to the joining of the sheet paths.
